TECHNICAL FEATURES AND OPTIONS

BENEFITS

• Optimal wearing resistance of the hardened sealing piston.• Compact slim design.• Different cracking pressure available upon request • Simple to use.

HOW TO USE

• Install the “VUZ” by matching the fl ow direction with the arrow stamped on the valve.

• To ensure a good effi ciency of the system, it is important to select correctly the valve based on fl ow performances, pressure drop and application. See the pressure drop graph.
